Gible is a Dragon/Ground type (very solid typing offensively, defensively it isn't as great of a typing, but still decent enough ; be cautious around the 4x ice weakness though) Then in terms of design, I like the way they designed Gible, and I tend to find it a really appealing pokemon and think it fits nice. Now, as far as battling capabilities go, like said already it is a good offensive typing with it having nice stats in both of its attacks, and has okay defensive stats / speed stat , and when it comes to movepool / abilities both those are pretty solid also. Overall, Gible is actually a great pokemon to use for both in game and competitive (at least think it's good in competitive, could be wrong) and I really do like this dragon, but compared to the stuff left, I just don't think it fit appeal anymore.
